CQMEINED MOISTENER AND FURNACE.

Application filed March 22, 1922. Serial Ito. 545,836.

To all whom it may concern:

Be it known that I, BERNARR MAorAoDEN, a citizen of the United States, residing in New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Combined Moisteners and Furnaces, of which the following is a specification.

This invention relates to combined heaters and moisteners, though the invention is not limited to heaters.

One object of the invention is to provide an apparatus or device of this kind in which the flow of water is regulated by the amount of heat or evaporation of the water.

Another object of the invention is to provide an apparatus or device of this kind in which there is a particularly efiicient form of evaporating channel for the water and a special arrangement whereby this channel is led past the door of the heater.

(Ether objects of the invention are to improve generally the' simplicity and efliciency of such devices and to provlde a device or apparatus of this kind which is durable, economical to manufacture and operate and which will not easil get out of order.

For the accomplishment of these and other objects my improved heater and moistener, briefly stated, comprise a heater provided with a door and an outer channel spiralling in reverse direction therearound, and a trough into which the channel discharges. A tank on the stove has a controlledoutlet discharging into the trough.

Uther objects of the invention will appear as the description proceeds; andwhile herein details of the invention are described, the invention is not limited to these, since many and various changes may be made without departing from the scope of the invention as claimed.

In the accompanying; drawings, showing by way of example two of many possible embodiments of the invention.

Fig. 1 is an axial vertical sectional View, partly in elevation of one form of invention;

Fig. 2 is a transverse vertical sectional view taken on the line 2-'2 of Fig. 1 looking in the direction of the arrow of said line;

, elevation.

Fig.3 is a vertlcal sectional view, partly in end 11 and adrip orifice 12.. An intermediate channel 14 receives the drip from said 'OIlfiCB and spirals in reverse dlrection,

to said door again and there is provided with a drip orifice 15 discharging into a lower spiral channel 16 discharging into the catch trough 7.

A tank 20 on the top of the stove is provided with an outlet valve pipe 21 having an adjustable cock 22 for discharge into said upper channel 10. An elbow lever 26 is fulcrumed at its elbow part at the inner face of the tank and carries a valve closure 23 for said outlet valve pipe 2l. A spring 24 engages the elbow lever for normally holding the valve pipe closed. A vaporizing fluid thermostat 25 engages the elbow lever for opening the valve'when the thermostat.

is heated, as by the water in the tank.

A water feed'pipe 27 secured to a bracket 28 secured to said tank feeds Water into-the tank and is automatically opened or closed by a float valve member 29 closing said feed pipe and provided with a float rod 30 and float 32 whereby the feed pipe is closed when the tank is partially full.

The operationof the device is very simple. The water is fed through the supply pipe 27 until-the float 32 rises and closes the float valve. The water heats in the tank and finally heats the thermostat 25 which opens the, outlet valve pipe 21 and the water drips into the spiral channel 10and gradually runs down through the orifice 11 and channels 14 and 16 to the catch trough 7, if it has not all evaporated before that time. The catch trough being around the fire box will evaporate all that comes to .it, the cock 22 being set not to give-more evaporation than is desired or more water than can be evaporated. As the water is drained from the tank 20, the float will lower and admit more. If the fire goes out the thermostat will close the outlet valve to prevent further water from flowing down the channels.

The drum 35 enclosing the whole stove adapts the arrangement for a jacketed stove or a hot air furnace; but if the drum be omitted, the furnace may be used as an ordinary stove. The drum is provided with a cold air inlet 36 and warm. air outlets 37 rod 30 upwardly offset and extending over the opposite edge of the tank 20' and carrying a vertical float rod 31 pivoted to the free end of said rod and carrying a float 32 secured to the float rod and disposed in said basin 9, whereby the feed pipe 27 is closed when the basin 9 is partially full.

The operation of the device of Fig- 3 is as follows:

The basin 9 being empty, the Water is fed through supply pipe and out the outlet valve and drips into the spiral .channel 10 and gradually runs down through the'orifices and lower channels to the catch trough and fills the basin until the float ri'ses'and closes the pipe 27 The catch trough being around the fire box will evaporate all the water that comes to it, and as the water evaporates, the fioatwill lower and admit more water. the fire goes out the water will not evaporate and thus run into the basin and raise the float to close the outlet valve. Excessive moisture may be prevented by nearly closing the valve cock 22'.
